My partner helps me with flexing and extending muscles working methodically on my affected side.
Beginning with my left toes (the paralyzed ones) he interlaces his fingers into my toes. It spreads the tendons that connct all the way up. It feels freaky. trace along the top of the tendon to the ankle, manipulating the tendon gently.. stretch and try to rotate the joint in its full rotation. (if it moves freely. Any resistance will be a trouble spot.) don't force it, - skip it and move on.
grip the calf muscle between thumb and forefinger and massage, finding and manipulating the tendons. each one will lead you to the next travelling up the body.
By to time you reach the arm pit you are pressing your middle fingers upward under the armpit, with your thumb pressing down ward from your neck.
the chain actually continues up the neck tendon under the jaw, and massage under the jawline of the mandibular joint muscles and base of tongue feels good and also relaxes the wrist. by direct referral.
Then (and only then) can i attain full WRIST rotation.
